The sources of thermal water for Pamukkale are about 20 km from Denizli. The ancient city of Hierapolis is also located in the same place. The water comes from underground karstic caverns and creates the cascades through precipitation of CaCO3 (calcium bicarbonate ) as the CO2 (carbon dioxide) evaporates.
Thermal spring water is beneficial for myocardium and cardiac complaints.
The curative value of this thermal spring was understood in ancient times as well. It has been used for centuries. During the Roman Era religious ceremonies and festivals were held at the thermal pools, and important statesmen and rich people came to Hierapolis to be cured. Religious functionaries and ancient physicians administered healing.
The spring waters are rich in calcium, magnesium sulfate, bicarbonate and carbon dioxide. They also have a radioactive content of 1,537 picocuries/liter. The pH is 6.0.
Travertine is a kind of rock which is formed as calcium bicarbonate precipitates out of hot spring water. It may be formed in many ways under different atmospheric conditions. Geological activity of the past affected a large area in which the Pamukkale thermal springs are found. There are 17 thermal sources in this special area with temperatures ranging between 35-100°C. The source of Pamukkale is only one unit of that whole area. The thermal water flows to the top of the cascades by a 320-meter-long channel and then flows on the cascades about 240-300 m. CaCO3 begins to precipitate on the cascades as the carbon dioxide evaporates, but in the beginning the precipitate is soft like gel. It needs time to completely dry and harden. In order to protect the cascades from destruction and to preserve their natural beauty, entrance to the travertine area has been prohibited since 15 May 1997. .
Weather conditions, the temperature of the water, and sufficient time for water tospread and flow are very important for the maintenance of white travertines. Precipitation goes on until the levels of carbon dioxide in the thermal water and the surrounding air are balanced. While the quantity of CO2 is 725 mg/l in the source, it is only 125 mg/l at the end of the travertines. Calcium bicarbonate also decreases from 1200 mg/l to 400 mg/l, and calcium decreases from 576 to 8 mg/l. Analysis indicates that 499.9 mg of CaCO3 precipitates per liter of thermal water over the cascades. The average density of the thermal water is 1.48 g/cm3 with a flow rate of 466.2 liters/second. That means 43,191 grams of calcium bicarbonate precipitate from the thermal water per day. Theoretically, that can whiten a 13,584 m2 area. However, whitening a 13,584 m2 area is practically very difficult. The whole travertine area currently covers 22,000 m2

Superb notes. The image has been beautifully caught. Having been there I know just how bright the white surfaces are and how difficult it can be to keep all the detail. Very well done.

Beautiful capture of the colours and the details. My only complaint is that I would like it to be rotated a bit CCW so that the planes of the pools would be horizontal. I feel the water is going to run off the right.

Welcome to TE.
Nice first submission the framing and composition is great. The colors are fantastic the white has retained good detail and the reflection is great.
I would suggesta slight rotation and the the drop shadow I find it slightly distracting.

I went there but I was not able to catch up the beauty of the place like you´ve done in this photo. Congratulations, I read that there were problems of water due to overexplotation, as I see in this photo, seems that they´ve find a solution. Great one, I look forward to see more of your job.

une vue parfaite de ce phénomène très particulier, bien colorée et très nette.
Du bon travail.
Merci pour le partage.

Very fine shot with this fabulous landscape of Pamukkale. It must be magical to have a bath there. I wish I could be there during these hot days of June... The compo and the graphism in general are very good.

Superb POV on this scenic geological curiosity. Light and contrasts are well managed and colors are totally surrealistic. Thanks a lot for the very complete and interesting explicative note and for sharing this nice piece of the world...

Very nice for this time.
During my visit in same place in 2000, Pamukkale was considered an affected natural site due to the permanent presence of numerous tourists.
Could we get same kind of pictures today?
Tracker (1942) 2005-10-04 3:15
Great! I took the pictures there and know that is difficult to save the absolutely white travertines on a film. Good compo, well done. tfs, regards.

May I join the others in welcomming you to TE. Hope you enjoy sharing your work with the others here as much as we do. Your first post shows us a very famous and much photographed place, but your additional information gives as extra value. Many thanks Fikret.

pamukkale is stunning. but it is better in pictures than in reality, when you have pictures like those that you see on Trek Earth.
great colors, very clear.
